Description

Varimax rotation is often used in factor analysis in order to make the factors easy to interpret. In this paper we apply the rotation to Hayashi's second method of quantification, and tries to make the category scores easy to interpret. The rotation is applied to the category scores standardized in terms of both the frequency-weighted mean and the within-group variance. A set of simple artificial data is presented to illustrate the method. Then the method is applied to two data sets: medical data on the aged with 9 groups, 62 individuals and 16 variables, and Fisher's iris data. Finally two results, those obtained by applying varimax rotation to canonical discriminant analysis and those obtained by applying the rotation to Hayashi's second method of quantification, are compared.
